Solving Absolute Value Equations Made Easy

This video tutorial by Mr. J covers solving absolute value equations, starting with a review of absolute value as the distance from zero. It explains solving equations with isolated absolute values and those with operations outside the absolute value. The video provides step-by-step examples, demonstrating how to isolate variables and check solutions. It aims to build a solid understanding of absolute value equations, preparing viewers for more complex problems.
